Description
Technical field
The present invention relates to a kind of general drop type fusion tube understructures, belong to distribution and make somebody a mere figurehead electric power instrument technology neck
Domain.
Background technology
Fuse switch is 10（20）KV distribution lines branch line and a kind of most common short-circuit protection of distribution transformer
Switch, it has the characteristics that economical, easy to operate, adaptation outdoor environment is strong, is widely used in 10（20）KV distribution lines
It is used with distribution transformer primary side as protecting and carry out equipment throwing, cut operation.Fuse switch is mounted on 10（20）kV
On distribution line branch line, scope of power outage can be reduced, because there are one apparent cut-off points for it, has the function of disconnecting switch,
A safety work environment is created to maintenance section circuit and equipment, increases the sense of security of service personnel.Become mounted on distribution
On depressor, can as the main protection of distribution transformer, so, 10（20）It is obtained in kV distribution lines and distribution transformer
It is universal.
In the prior art, fuse switch is mainly by insulator foot 101, dynamic/static contact 102,103 three parts of cartridge fuse
Composition, as shown in Figure 1, wherein insulator foot 101 includes the silver-plated lower copper that 103 bottom of cartridge fuse is fastened on by holding pin 104
First 105, a ferrule-based fittings 107 are connected to by a rotational pin 106 on the lower copperhead 105, the ferrule-based fittings 107 and a fuse pressure
Plate 108 connects, interior to be equipped with spring 109 by bolt；The upper end of cartridge fuse 103 is socketed with top copper screw cap 110, and lower section is logical
It crosses holding pin 111 and operation ring 112 is installed；
The moving contact at cartridge fuse both ends is fastened by fuse (melt), behind upper moving contact push-in " duckbilled " protrusion part,
Upper static contact heads on moving contact made of phosphorus bronze sheet etc., so to be stuck in " duckbilled " securely inner for cartridge fuse.When short circuit current is logical
When crossing fuse failure, electric arc is generated, the vulcanized fiber tube of cartridge fuse liner generates a large amount of gas because on cartridge fuse under arcing
End is shut, and gas is sprayed to lower end, blows out electric arc.Due to fuse failure, what the upper lower moving contact of cartridge fuse lost fuse is
Clamp force, under the action of cartridge fuse its own gravity and upper and lower static contact spring leaf, cartridge fuse falls rapidly, and circuit is made to disconnect, and cuts
Except faulty section circuit or faulty equipment.
Existing fuse switch is and easy for installation because it has the function of the fuse protection of excess load, and operation is flexible, quilt
Middle pressure network frame generally uses.But due to Commodity Centralism Purchase bid winner difference, the drop type used on middle pressure network frame now is molten
Disconnected type number is more, generally reaches 6 kinds, though the pattern of the fuse switch fusion tube of these different models it is similar all it is each not
Equally, upper moving contact（Also referred to as top structure）Size shape and position are differed can not be general；Especially early application is in net
Old model on frame, manufacturer's not fuse switch and standby redundancy of reproduction same type, causes repairing goods and materials
Shortage, single fusion tube, which is burnt out, will be related to deactivating upper level power supply, expand scope of power outage, extend repairing duration, to high-quality
Service affects greatly.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and offer is a kind of reasonable for structure, compact, uses peace
Convenient, good reliability is filled, various fuses can be suitble to match, reduces the deposit of repairing spare unit, power failure is reduced and robs
Repair the general drop type fusion tube top structure of duration.
The purpose of the present invention is by following technical solution to complete, a kind of general drop type fusion tube of the present invention
Top structure, it mainly by being socketed in the operation ring set circle, upper moving contact lasso and top pullover of fusion tube upper end successively respectively,
Disjunctor has wedge contact body and stick contact body respectively on the upper moving contact lasso.
Pin hole is offered respectively on the operation ring set circle and upper moving contact lasso, and being each configured with can will grasp thereon
Make ring set circle and upper moving contact lasso is adjustably fixed on holding pin on the corresponding position of fusion tube upper end.
The present invention has reasonable for structure, compact, easy to install and use, good reliability, can be suitble to various fuse pedestals
The features such as matching, reduce the deposit of repairing spare unit, reducing power failure repairing duration.
Description of the drawings
Fig. 1 is existing fuse switch structural schematic diagram.
Fig. 2 is the top structure schematic diagram of fuse switch of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be described in detail：Shown in Fig. 2, a kind of general drop type of the present invention
Fusion tube top structure, it mainly by being socketed in the operation ring set circle 2 of 1 upper end of fusion tube, upper moving contact lasso 3 and top successively respectively
Portion's pullover 4, disjunctor has wedge contact body 5 and stick contact body 6 respectively on the upper moving contact lasso 3.
As shown in the figure, pin hole 7 is offered respectively on the operation ring set circle 2 and upper moving contact lasso 3, each autogamy thereon
It is equipped with the holding pin 8 that operation ring set circle 3 and upper moving contact lasso 4 can be adjustably fixed on 1 upper end corresponding position of fusion tube.
Upper moving contact at the top of fusion tube is designed to be adjusted apart from the depth into tube body by the present invention, is melted to reach to adjust
The effect of length of tube, to adapt at the top of different fuses；It is by three kinds of top of existing fuse, wedge shape and bar type fusion tubes
Top shape is fused into a kind of adjustable universal fusion tube top, while ensureing every electric property of general shape fusion tube；
In actual use, it is only necessary to carry out the fixation of upper moving contact body after being rotated at the top of fusion tube when installation again.
Fusion tube of the present invention is insulating materials, is respectively conductive material at the top and bottom of fusion tube；Fusion tube bottom is logical
It crosses screw to be fixed, adjusting screw can freely adjust the direction of top and bottom distance, the direction at top and operation ring.
